If I had this, my life would be COMPLETE! Behold, the most amazing thing you'll see today: perpetual Slinky treadmill. God knows how many laws of thermodynamics this lil' puppy has broken* just today (no actual treadmill required and less complicated than the Slink-O-Matic!)

Actually, it's the NESM or Never Ending Slinky Machine, by the folks over at Creatables. The Slinky treadmill is powered by USB connection and is perfectly angled to keep your Slinky "slinking" downhill as long as you keep the treadmill powered.

It's the perfect accompaniment to The Most Useless Machine you've undoubtedly got in your cabinet of curiosities (what? you don't have one?)
